Ok, This is what I did so far
Homed my machine to the limits, this is also machine 0.
Called for Tool 0 at the above location in the MDI line. Set X part zero and Z part zero and hit apply, save.
Then I went to tool 4 and touched the x, installed the diameter in the X part zero, hit touch X, apply, save.
Same for tool 6.
At this time tools 4 and 6 would and will repeat and end up in the correct location.
However when I try to run the procedure on tool 1, I touch in X, install diameter in the X Part Zero dro, hit touch X, apply, save.
I have then tried to touch Z and just hit 0 in the Z axis dro apply, save and I have tried it with the Z part zero dro with a 0 value, touch Z apply, save.
If I call tool 1 and procede to G1 Z0 X0 F8 (for example) the X immediately starts going the wrong direction and faults the limit switch.
Btw I still get different speeds of approach to the part depending on the tool number requested, regardless of the F rate. Once I get a little better grasp on the toolchanger set up, I am deleting all of Mach and doing a fresh install.
Thanks
